To all whom t may concern.'

Be it known that I, JOHN HOWARD WAY,

-of Philadelphia, county of Philadelphia,

State of Pennsylvania, have invented certain new and useful Improvementsin Concealed or Invisible Butt-Hinges, whereof the following is aspeciicatiomreference being had to the accompanying drawings.

The invention relates to improvements in hinges, and especiallyconcealed or invisible butt-hinges, such as are ordinarily employed inmounting the doors of automobiles Vor coaches on their supportingstructures.

The present invention is directed more particularly to a simple, novel,and inexpensive fulcrum structure, whereby the operative relationbetween the two constituent elements of the hinge may be readilyadjusted to facilitate the fitting of the doors to their mountingswithout requiring absolute accuracy in initial assembling.

The structure, whereby, I attain the advantage above pointed out will bebest understood from the detailed description which follows:

In the drawings, Figure I. a plan view of a hinge structure convenientlyembodying my invention.

Fig. II. is a sectional elevation of the same, and Fig. III. is aperspective of the hinge pin.

The hinge herein shown comprises. a fixed member in the form of a faceplate 1, having a laterally projecting bracket, which is concealedwithin an opening initially prepared in the pillar post, or frame towhich the door is hung. This face plate may be secured by any approvedmeans, and in the present in stance is provided with countersunk holes3, for the reception of screws, by which attachment may be effected.

The movable member of the hinge is in f the form of an arcuate arm 5,which is operative through an opening 4, in member 1, and has a pintleconnection with the bracket 2. Integrally formed With the movable member5, is a face plate 6, similar to that of member 1, and likewiseIprovided with countersunk hole's 7, for the reception of attachmentmeans, by which it is secured to the door.

The fulcrum or pintle member or structure of the hinge includes a pinportion 10, received in .a hole in the terminal boss 11, of the arcuatearm 5, and capable of being rotatably 4adjusted therein. Such adjustmentis fixable by a nut 12, engagi11g-the protruding threaded upper end ofthe pin,

and clamping against the adjacent face of the boss 11. Said pinisfurther provided with an eccentric pintle portionor extension 13,engaged in a hole in a bearing lug 14, formed on the bracket 2, of themember l. The intermediate portion or collar 15, of the pin, serves as abearing member in cooperation .with the lug. 14, and is also furtherfunctional in opposition to the nut 12, in effecting the clamping of thepin in its adjusted positions. n

In practice, `when it is .n desired Yto adjust the door with respect toits mounting, it is simply necessaryto loosen the nut 12, engage the pinby means of a screw-driver or other suitable implement, (slot 16 beingprovided for'this purpose) and to turn the same until the desiredadjustment is secured, whereupon, the nut may again be clamped as isalready understood. In the course of such adjustment, it Will be readilyseen that by virtue of the eccentric disposal of the extension 13, ofthe pin 10, the movable member 6, (and the attached door) will beshifted'relative to the fixed member 1, (and the door mounting). Y

If desired, provisions may be made in the mounting frame of the doorstructure, so that access, for the purpose of adjustment may be had tothe pin 10, from the exterior without detaching the door. However, ifthe other alternative should be deemed advisable, the structure of thehinge is such as to permit ready dismounting of the door, since theopening 4, in the plate 1, is of ampie dimensions to permit withdrawalof the member 5, together with the attached fulcrum pin 10, withoutdanger ofdisplacement either before or after, the adjustment is made. r

Having thus described my invention, I claim:

l. In a concealed hinge, the combination of a fixed member, or faceplate; a movable memberor hinge arm operative through an opening in thefixed member; and a fulcrum structure comprising a pin rotatablyadjustable in one of said members and provided with an eccentricextension pivotally engaged in the other, and also having anintermediate bearing collar coperative the rotary adjustment of saidpin, and

adapted to engage with the-bearing support Y on the xed member.

2. In la hinge, the combination of. fixed and movable hinge members eachhaving a hole therein; a fulerlun member having a pintle portionpivotally engaged in the hole in one of said hinge members, a pinportioneceentric to said pintle portion rotatable for adjustment in andextending through the other of said hinge members, and screw' threadedon its projecting end, and an in: termediate enlarged collar portioninter- 1 posed between said hinge members, abutting against the onecontaining the pin and I bearing against the other in their relativemovement; and a nut on the projecting threaded end of the pinmembercoacting with said collar to clamp and secure said v fulcrum member 4inadjusted position in the JOHN HOWARD WAY.
